چکیده
Indoor optical wireless communication systems offer a huge potential to provide high speed data transmission for various indoor applications like in flight entertainment, video transmission and other multimedia services. These systems use LEDs as the source which can transmit and receive data by flashing light at a speed which is undetectable to the human eyes. In this paper we review the deployment of optical wireless systems for different applications and the use of multiple transmitters and receivers (MIMO) in order to ensure low Bit Error Rate (BER) along with high data rates.

A Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets
A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...

For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...
